Method for urgently blocking river dam breach based on array rocket drilling ground anchor

Abstract

The invention discloses a method for urgently blocking a river dam breach based on an array rocket drilling ground anchor. The method comprises the following specific steps that (1) the rocket anchor is launched, an anchor cable is connected with a shore fixed pile, and a 'rooting strongpoint' is formed at the dam breach; (2) steel mesh stone cage sets are slidably thrown through the rocket anchor cable, and a 'tower of strength' for dam breach blocking and repairing is rapidly formed; and (3) through an anchor dot array, steel mesh stone cages are slidably thrown and connected to form an 'expanding main body' for dam breach blocking and repairing. Precise arraying is conducted through laser guidance, meanwhile, anchor tools are triggered and expanded through sensing, the anchor tools are firstly fixedly arranged and then combined to increase the area, thus a preset anchor array is rapidly formed at the dam breach, and then the steel mesh stone cages are slidably thrown through a plurality of channels to construct a blocking and repairing main body. The technology is based on the high technology and adopts interdisciplinary innovation, the situation that military products are used for people is developed, the important technical problem of river treatment is solved, and wide application prospects and huge social and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of blocking rivers and lakes, and in particular relates to a method for blocking river breaches based on array rocket-drilled ground anchors. Background technique [0002] my country is a country prone to floods, and dam breaches caused by floods during flood seasons seriously threaten local agriculture, transportation, ecological environment, and the safety of residents' lives and properties. At present, for some large-scale breaches with large drop and high flow velocity, it is often difficult to quickly block them with existing rescue technologies. It is obviously not a scientific and efficient method to save time or even sink ships and vehicles. At present, most domestic and foreign breaches are blocked by horizontal plugging method, vertical plugging method, mixed plugging method, etc., but there are disadvantages such as low efficiency, long time-consuming, high cost, and high risk for large-scale brea...

Problems solved by technology

At present, for some large-scale breaches with large drop and high flow velocity, it is often difficult to block them quickly with existing rescue technologies. It is obviously not a scientific and efficient method to save time and even sink ships and vehicles.

At present, most domestic and foreign breaches are blocked by horizontal plugging method, vertical plugging method, mixed plugging method, etc., but there are disadvantages such as low efficiency, long time-consuming, high cost, and high risk for large-scale breach plugging. Therefore, it is necessary to find a high-efficiency , fast and safe new plugging technology to solve the above problems
